为了充分探究睡眠对认知的作用机制,睡眠剥夺是一个有效的途径。目前有多种手段研究睡眠剥夺如何影响认知功能,包括认知心理学评价、脑成像方法、脑电生理的变化等。所研究的方面覆盖认知科学的多个领域,目前国内外均有学者致力于此研究,并已经取得了初步的成果,但是存在多种影响因素,尚未得到统一的结论。我们从睡眠剥夺引起认知功能下降的机制出发,综述了通过脑成像方法研究神经生理学变化以及脑电生理方法评价认知功能下降的研究进展,并分析研究的影响因素和目前关注的发展方向。
In order to fully explore the mechanism of sleep on cognitive function, sleep deprivation is an effective way. There are many ways to study how sleep deprivation affects cognitive function, including cognitive psychology, brain imaging, changes in brain electrophysiology. The research area covers many fields of cognitive science. At present, scholars both at home and abroad devote themselves to this research and have achieved preliminary results. However, there are many influencing factors and no unified conclusion has been reached yet. Starting from the mechanism of cognitive impairment caused by sleep deprivation, we reviewed the research progress of neurophysiological changes by brain imaging and the evaluation of cognitive function by EEG. And we analyzed the influencing factors and the current development direction.
